You can also specify particular cards render at the currently selected Render Priority. To do this, tick the Use Priority checkbox, and then select High, Medium or Low as the Render Priority. If you are using a single card for both Cuda rendering and as you Windows display adapter, it is recommended that you select the Low Priority. Remember to click Apply to apply a changed Render Priority to your video card.

Important:

1. If you have an on-board graphics card (or second graphic card), use it as your Windows display adapter
2. If you do NOT have an on-board graphics or second graphics card to use as your Windows display adapter, set the Render Priority of your card to Low (as described above).
3. If you get an Nvidia driver crash, this is due to a time-out. In this case, install Octane Standalone (since the installer will change the Nvidia time-out settings), and set the Render Priority of your card to Low (as described above).

In the unlikely event that you get a Cuda error from your video card, click the Cuda Errors button to display specific details on the error.

For troubleshooting problems, refer to the topic in the OctaneRender™ Standalone Edition User Manual.
